Definitions
- the subject matter described herein generally relates to touch systems, such as capacitive touch pads, touchscreens, and the like, and more particularly relates to methods for operating such touch systems with multiple manipulator types.
- Touch systems such as touchscreen displays, touch pads, and the like, have become an increasingly popular type of input/output device, and are often used in connection with smartphones, e-book readers, table computers, and other such computing devices.
- touch systems are capable of being operated using multiple manipulator types. That is, the user may employ one or more fingers, fingernails, and/or a stylus to interact with the system, and the system attempts to adjust the gain and other input settings applied to touch events based on the manipulator type.
- FIG. 1 depicts a touch system useful in describing the present embodiments
- FIG. 2 illustrates a signal profile associated with a touch event produced by an exemplary manipulator
- FIG. 3 illustrates a signal profile associated with a touch event produced by an exemplary manipulator
- FIGS. 4 and 5 illustrate signal profiles and threshold attributes in accordance with one embodiment
- FIG. 6 is a flow chart illustrating an exemplary method in accordance with one embodiment.
- FIG. 7 is a conceptual block diagram of various modules executed by an exemplary processor.
- the subject matter described herein relates to systems and methods for distinguishing between manipulator types (e.g., a finger, a stylus, etc.) based on a threshold metric that includes, for example, a threshold amplitude and a threshold cross-sectional area or other attribute of a signal profile associated with a touch event.
- a threshold metric that includes, for example, a threshold amplitude and a threshold cross-sectional area or other attribute of a signal profile associated with a touch event.
- FIG. 1 is a conceptual overview of an exemplary touch system 100 useful in describing various embodiments.
- a touch sensor component 110 is configured to interact with various manipulators, such as a human finger 130 , or a stylus 140 .
- manipulators such as a human finger 130 , or a stylus 140 .
- Each type of manipulator when in contact or close proximity to touch sensor component 110 (e.g., in regions 131 and 141 , as illustrated), produces a signal that can be received and interpreted as a touch event by a processor 102 , which is suitably configured (through any combination of hardware and software components) to determine the location and any other selected attributes of regions 131 and 141 .
- Touch sensor component 110 may be superimposed upon a display 120 , viewable by a user 105 , thereby forming what is conventionally known as a touchscreen display.
- touch system 100 may include one or more of a variety of different types of displays 120 and sensor components no known in the art for displaying information and receiving input from a manipulator. Examples of such displays include capacitive displays, resistive displays, surface acoustic wave (SAW) displays, optical imaging displays, and the like.
- Display 120 may also provide haptic feedback to the user—e.g., a clicking response or keypress feel in response to a touch event.
- Touch sensor 110 may be combined with display 120 and fabricated as an integral device, or may be utilized within a display 120 .
- the present embodiments contemplate any suitable touch sensitive surface or sensor.
- FIGS. 2 and 3 depict example signal profiles 200 and 300 corresponding, respectively, to a typical stylus and a typical human finger. More particularly, profiles 200 and 300 consist of a series of detected signal levels along the surface of touch sensor component 110 (z-axis), where the x and y axes correspond to spatial position on the surface. Stated another way, signal profiles 200 and 300 can be seen as two-dimensional manifolds within a three-dimensional space, as shown, that uniquely characterize their respective touch events. These shapes can be analyzed (e.g., to determine area, shape, etc.) as described in further detail below. The analyzed shapes thus become a geometrical “signature” of the touch event.
- acoustic sensors such as piezo crystal sensors
- the touch profile can be determined and subsequently analyzed based on its acoustic characteristics.
- the traditional sensing threshold 210 is set too high (e.g., for a human finger input mode)
- the stylus signal profile 200 will not trigger a touch event, as the peak 202 is well below threshold 210 .
- threshold 310 is set too low (i.e., for a stylus input mode)
- peak 302 of finger signal profile 300 will be much greater than threshold 310 , and is likely to result in “false positives”—i.e., touch events that are triggered erroneously in response to proximity of the user's finger.
- systems and methods are provided for distinguishing between manipulator types based on one or more attributes of the signal profile (e.g., shape, size, area) at one or more predetermined threshold signal values.
- the system analyzes a cross-section of the signal profile along a plane that is orthogonal to the z-axis at a threshold value (i.e., the portion of the signal profile that exceeds the threshold signal value).
- the cross-section is analyzed to determine its area, shape, perimeter, aspect ratio, or any other geometrical attribute or signature, and that attribute is then used to determine the type of manipulator corresponding to the signal profile.
- the system then switches to the correct input mode, adjusting the signal gain and other parameters accordingly.
- the total area of the cross-section at a threshold signal value is the particular attribute used to distinguish between manipulator types. That is, as shown in FIG. 4 , the system utilizes multiple predetermined threshold values, such as the exemplary two illustrated: threshold value 411 (which may correspond, for example, to a finger threshold value), and threshold value 412 (which may correspond, for example, to a stylus threshold value). The system also knows, a priori, two cross-sectional area values: threshold cross-sectional area 421 , and threshold cross-sectional area 422 , corresponding respectively to threshold values 411 and 412 . As illustrated, threshold value 412 is less than threshold value 411 , and its area 422 is less than area 421 . This corresponds generally to the finger/stylus distinction described earlier in connection with FIGS. 1 and 2 . In any particular embodiment, any number of such areas and threshold values may be used, each corresponding to a different type of manipulator.
- threshold value 411 which may correspond, for example, to a finger threshold value
- the system examines the cross-sectional area at threshold values 411 and 412 and determines whether that area is substantially equal (within some reasonable tolerance) to corresponding area 421 or 422 .
- This tolerance which will generally vary depending upon the nature of the touch screen sensor, may be selected based on empirical testing, computer modeling, or through any other method known in the art.
- FIG. 4 shows a finger signal profile 300
- the cross-sectional area at threshold value 411 is substantially equal to area 421 , but much greater than area 422 .
- the system would then consider the “threshold” for the finger-type manipulator to be met.
- FIG. 5 shows the case of a stylus signal profile 200 that meets the threshold for a stylus-type manipulator.
- FIG. 6 is a flowchart depicting an exemplary method in accordance with one embodiment. While this example is described in the context of two types of manipulators—stylus and finger—the invention is not so limited, and may be used in connection with any number and type of manipulators.
- the process begins ( 602 ) in response to user input, power-up, or any suitable event.
- the system enters human finger input mode ( 604 ). This default condition is particularly advantageous in cases where a stylus or other manipulator is stored in a cavity in a mobile device, and user would, for the purpose of convenience, generally prefer to use a finger for input whenever possible.
- the system configures the touch system for human finger input detection.
- the system gain i.e., the gain used to produce the signal profile
- the threshold values described above are scaled based on the expected signal during human finger input mode (step 610 ).
- step 612 the system waits for a touch event.
- Such events may include a variety of conventional events indicating interaction of a user with a touch surface, e.g., single presses, multi-touch, dragging, gestures, and the like.
- step 616 the system queries whether the finger threshold is met. That is, the magnitude of the cross-sectional area of the signal profile at the finger threshold value (as described above) is compared to the predetermined area value. If the two are substantially the same, then the procedure continues with step 618 , reporting touchscreen information in a loop as illustrated.
- the touchscreen information may be reported as position data, as an interrupt, or in any other manner depending upon the nature of the software utilizing the information.
- step 616 the process continues with step 614 and queries whether the stylus threshold is met. That is, the cross-sectional area of the signal profile at the stylus threshold value (as described above) is compared to the predetermined area value. If the two are not substantially the same, then the procedure proceeds back to step 612 and waits for a touch event. If the stylus threshold is met, however, the process continues to step 620 and begins stylus input mode.
- step 622 the touch system is configured for stylus input detection. As with step 606 above, this step will typically involve adjusting the gain and threshold values so that they are suitable for interpreting stylus touch events (steps 624 and 626 ). Subsequently, in step 628 , the touchscreen event information is reported.
- step 630 the system initializes and starts an idle activity timer, and then waits for the next touch event (step 632 ). If, after the touch event, the stylus threshold is met (step 636 ), the procedure loops back to step 628 , and continues as before. If not, or if the idle activity timer has expired (step 634 ), the procedure loops back to step 604 , reverting once again to finger input mode.
- any number of such threshold may be used.
- the systems and methods described above may be implemented in a variety of devices, including, for example, cellular phones (or “smartphones”), GPS systems, e-book readers, tablet computers, netbook computers, point-of-sale devices, gaming devices, pen pads, and any other apparatus that may include a touch system.
- cellular phones or “smartphones”
- GPS systems GPS systems
- e-book readers tablet computers
- netbook computers netbook computers
- point-of-sale devices gaming devices
- pen pads and any other apparatus that may include a touch system.
- touch system any other apparatus that may include a touch system.
- such devices are typically special-purpose or general-purpose computing devices including one or more microprocessors, memory components, and the like as is known in the art.
- processor 102 may include a touch detection module 702 , a signature computation module 704 , a manipulator determination module 706 , a mode selection module 708 , and a gain controller 710 .
- Touch detection module 702 generally detects touch events and determines a signal profile associated with the sensor signal.
- Signature computation module 704 calculates an attribute of the signal profile at a threshold signal value—for example, a geometrical attribute of the cross-sectional area at the threshold signal value, or any other suitable attribute that can provide a “signature” associated with different manipulators.
- Manipulator determination module 706 determines the type of the manipulator based on the computed geometrical attribute, and gain controller 710 adjusts the gain of the signal profile, the geometrical attribute, and the threshold level values as described above.
- a computer program product in accordance with one embodiment comprises a computer usable medium (e.g., standard RAM, an optical disc, a USB drive, or the like) having computer-readable program code embodied therein, wherein the computer-readable program code is adapted to be executed by processor 102 (working in connection with an operating system) to implement a method as described above.
- the program code may be implemented in any desired language, and may be implemented as machine code, assembly code, byte code, interpretable source code or the like (e.g., via C, C++, Java, Actionscript, Objective-C, Javascript, CSS, XML, etc.).
